As a former sheep farmer, I was fascinated with using wool for insulation. I was aware of the concept because I've interviewed numerous farmers around the Gulf Coast who no longer have local wool processors. When I asked them what they did with the wool after annual shearing, they often cited insulating their barns! The more research I do on this product, the more advantages I find. Getting the actual product and comparing it to wool from my former sheep was fun and informative, especially for contractors unfamiliar with it. I'm obsessed! I'll look forward to a further review after installation.

Feels beautifully soft and natural and NO SMELL for chemically sensitive people like myself. I will be purchasing Havelock Wool for our new build.
